E LE CIRIC LIGHTING DE VICE Application filed October 28, 1907.

To all whom it may concern:

Be it known that I, Josnua T. FISK, a citizen of the United States,resident of Rochester, county of Monroe, and State of New York, haveinvented a new and useful Improvement in Electric Lighting Devices, ofwhich the following is a specification, the principle of the inventionbeing herein explained and the best mode in which I have contemplatedapplying that principle, so as to distinguish it from other inventions.

My invention relates toelectric lighting devices adapted for use as acigar-lighter to enablea smoker to light a cigar while in rapid motionor otherwisefbu t it is applicable for use as a cigar-lighter on thecounters of stores or other places.

The invention furthermore relates par ticularly to that class of devicesshown, described and claimed in the application Serial No. 393,418,filed September 17, 1907, by Clarence lVheeler, and consists in anarrangement of parts which while in its general features is identicalwith the invention of said Wheeler, yet contains certain otherimprovements diifering materially therefrom.

The said improvements are hereinafter fully described and specificallyset forth in the claims.

The object of said invention is to increase the efficiency of the deviceby decreasing the time which is ordinarily consumed in raising theresistance wire to the required temperature, increasing the degree ofheat produced by the incandescence of such wire, without increasing theconsumption of current.

The annexed drawing and the following description set forth in detail,certain mechanism embodying the invention, the disclosed meansconstituting but one of various mechanical forms in which the principleof the invention maybe applied.

In said annexed drawing :Figure 1 represents a perspective view of alighting device embodying my invention, showing its parts arranged foruse as a cigar lighter. Fig. 2 is a greatly enlarged axial sectionalview through the front portion of the device. Fig. 3 is across-sectional view taken on line 33 of Fig. 2. Fi 4 is a similar viewtaken on line 4.4t 0 Fig. 2; and Fig. 5 is a view in side elevation ofthe front portion Specification of Letters Patent.

of the device, showing an electric lamp provided with a reflectorconnected thereto.

Like numerals of reference, refer to corresponding parts throughout thedifferent views of the drawing.

The device illustrated shows a form of device to which my invention isapplied, which may also be used as an illuminant.

The reference numeral 10 designates the body or hand piece of thelighting device, which may be made of any suitable size, form andmaterial, but preferably cylin drical in shape and of wood or hardrubber. This body or hand piece is provided with a longitudinal bore 11,which is divided near its front end by means of a transverse partition12, thus forming two compartments 13 and 1 1 of the bore for thereception and operation of the various parts of the device, as will behereinafter explained.

Located in the compartment 1 1 of the bore 11 is an internalscrew-threaded metallic socket 1? which rests at its inner end on asuitable block or plug 16 interposed between said socket and the frontsurface of the partition 12, as is clearly shown in Fig. 2 of thedrawing. This plug and the partition 12 are apertured for the receptionof a terminal 17, to one end of which is connected one of the conductors18 which are extended through the rear end of the hand piece 10forwardly, and are connected at their other ends to a battery or othersource of electric supply. The other conductor 18 is also extendedthrough suitable openings in the partition 12 and block or plug 16 so asto contact or be electrically connected at its front end with themetallic socket 15, as is clearly shown in Fig. 2 of the drawing.

Located in the socket 15 is a stem or stub shaft of a removable cup 19,which is provided in its wall with a push-button 20 to coact with acontact spring 21 which is located in the cup, as shown in Figs. 2 andat of the drawing. The stem of the cup 19 consists of an externallyscrew-threaded metallic portion 22, which is hollow and of suitablelength to extend near the bottom of the socket 15 when screwed therein,and of insulating material 23, such as fiber, which is interposedbetween the screw-threaded extension 22 and a metallic rod 2%, usuallyof brass, which rod has in its front end a screwthreaded socket 25, andits other or rear end exposed to contact with the terminal 17 to whichone of the conductors is attached.

Removably located in the cup 19 is an i 'niter carrying cup 26, whichhas its front end open and its rear end closed by means of a disk orplate 27, of fiber or other suitable material, which plate or disk iscentrally apertured for the reception of a screw-bolt or pin 28, whichis flattened to prevent it turning in said disk when said pin or bolt isscrewed into the socket 25 of the metallic rod 24. The pin or bolt 28extends forwardly through the disk 27, and is provided in its forwardend with a slot 29 for the reception and retention of one end oftheigniting wire 30, which is convolute and of suitable material, and hasits other end secured in the slot 31 of a metallic post 32 which isextended through the disk 27 so as to pro ject beyond each of itssurfaces and so that its inner portion may be in position to be impingedagainst or contacted with by the contact spring 21 when pressure isapplied to the push-button 20 of the cup 19.

Located within the igniter carrying cup 26 is a bushing or plate 33, oflavite or other suitable material, which is formed with a centralopening for the reception of the pin or bolt 28 and also with an openingnear its periphery, through which is extended the front portion of thepost 32, which portion, as before stated, is slotted and holds one endof the igniting wire. The plate or bushing 33 is provided with anannular flange 34;, which extends outwardly within the cup 26, and saidbushing has on its front surface a number of radially disposed ribs 35to assist in supporting the wire 30. These ribs are of a depth less thanthe flange 3%, thus allowing the wire 30 to rest on their outer edges,yet to lie within the compartment formed by said flange. Resting on theflange 3 1 and externally of the wire 30 is a perforated disk, of micaor other suitable material 36, over which is laid a perforated disk 37,of very thin steel, the perforations of which register with those of thedisk 36, of mica. The steel or metallic disk 37 is employed to protectthe mica disk in the operation of lighting cigars, thus rendering itmore durable.

From the foregoing and by reference to the drawing it will be seen andclearly understood that when the parts are assembled as above describedand the conductors 18 are in electric communication with a generator, bypressing on the push button 20 the contact spring will be forced intocontact with the post 32, thus completing the circuit so that the wire30 will become heated to a high degree, when by applying the end of acigar to the perforated plate 37, it may be ignited.

By providing the bushing 33 with the flange 34 an air space 38 is formedbelow the resistance wire where in the device shown and described in theapplication of Vheeler, such wire rested directly upon an asbestossheet. By providing this air space I have found that the wire heats muchmore rapidly and to a higher temperature than was the case when no suchspace was provided. Such increase in time of heating and in temperaturematerially increases the efficiency of the device.

While I have shown the mica protecting disk 36 covered by the perforatedsteel disk, I have found that it is not absolutely essential to providethe latter and same may be omitted if desired.

Other modes of applying the principle of my invention may be employed,instead of the one explained and change may be made as regards themechanism herein disclosed, provided the means covered by any one of thefollowing claims be employed.

I, therefore, particularly point out and distinctly claim as myinvention:

1.
